This map shows recent unrest at Kīlauea volcano. Yellow circles mark earthquake locations from January 31, 2024 through 6:00 a.m. HST February 2, 2024, as recorded by HVO seismometers. Seismicity began early January 31 in the summit region and shifted to the southwest along the Koa‘e fault system late on January 31, 2024. In total, over 1,300 events have been detected in this area since January 31. Depths have remained consistent, 1–4 km (less than a mile–2.5 mi) below the surface, and the rates have persisted at 20-35 locatable earthquakes per hour. Magnitudes range from less than 1 to a maximum smaller than 4. Colored fringes in the map indicate areas of ground deformation from January 17–31, 2024, as measured by satellite radar. Each color cycle represents 1.5 cm (0.6 in) of ground motion toward the satellite, indicating a pattern of ground motion associated with magma accumulation. Global positioning system (GPS) instruments have recorded up to 8 inches (20 cm) of motion at stations in this area, consistent with magma moving into a dike-like body in the region. A dike is a tabular body of magma in older existing rock.

This image shows ground deformation during the recent intrusive activity at Kīlauea volcano. Unlike previous shared interferograms, note that this one is isolated to a one-day timeframe from 6 p.m. HST on January 31 through 6 p.m. HST on February 1, 2024. It therefore highlights the volcanic signals, with reduced interference from sources of data noise. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation.  Each color cycle represents 1.5 cm (0.6 in) of ground motion toward or away from the satellite (the direction of motion depends on the sense of color change).  The complex patterns indicate overall deflation of the summit area as magma moved underground to the southwest, where the patterns show uplift (up to about 50 centimeters, or 20 inches) and spreading (along with subsidence) due to intrusion of a dike (a vertical sheet of magma). Comparing this to the previous image, which was posted earlier today and that spanned up until January 31 at 6 PM, shows that the dike intrusion moved farther to the SW, consistent with patterns of seismicity. Data are from the COSMO-SkyMed constellation of radar satellites, provided by the Italian Space Agency (Agenzia Spaziale Italiana) through the Hawaiʻi Supersite.

Unrest continues at Kīlauea with heightened seismic activity and ground tilt changes. On January 31, HVO geologists were stationed on the west rim of Kaluapele (Kīlauea caldera) to document the onset of any eruptive activity at the summit. Numerous earthquakes shook the rim and frequent rockfalls occurred on the walls of Halema‘uma‘u crater. but an eruption did not occur. Earthquake activity quieted down later in the day, but later migrated along the Koa‘e fault system, where it is ongoing. USGS photo by M. Patrick.

Recent maintenance work was done on the KWcam (webcam) and F1cam (thermal camera), which are primary cameras used for monitoring activity at the summit of Kīlauea. USGS photo by M. Patrick.

Hawaiian Volcano Observatory geologists visited HVO's former office at Uēkahuna bluff, on Kīlauea's caldera rim, for likely the last time. Their job was to remove the remaining webcams in the observation tower of the Okamura Building, above the former Jaggar Museum. Here, one of the geologists dismantles a webcam with Mauna Loa volcano in the background. USGS photos by M. Zoeller.

The Okamura Building, which previously housed the USGS Hawaiian Volcano Observatory, was damaged during the summit collapse of Kīlauea in 2018. Deconstruction of Okamura Building is planned as part of the Hawaiʻi Volcanoes National Park 2018 Disaster Recovery Project. For more information on Hawaiʻi Volcanoes National Park 2018 Disaster Recovery Project, see https://www.nps.gov/havo/learn/management/jaggar-museum.htm. 

The KIcam, KW2cam, KEcam, and M1cam were removed from the observation tower of the Okamura Building. These webcams have also been removed from the Hawaiian Volcano Observatory website.

KIcam, KW2cam, KEcam provided views of Kaluapele (Kīlauea caldera). Several other webcams provide alternate views of Kaluapele (Kīlauea caldera):

• [F1cam] Halemaʻumaʻu thermal image from the west rim of the summit caldera, looking east
• [V1cam] - Kīlauea caldera views
• [B1cam] - Kīlauea caldera down-dropped block and Halemaʻumaʻu
• [B2cam] Halemaʻumaʻu crater from the east rim and down-dropped block
• [K2cam] Kaluapele (Kīlauea caldera) from Uēkahuna bluff | U.S. Geological Survey (usgs.gov)
• [KWcam] Halemaʻumaʻu, lava lake, and down-dropped block from the west rim of the summit caldera, looking east

The M1cam provided a view of Mauna Loa's Northeast Rift Zone. A webcam with views from a similar vantage will be provided soon.

In the meantime, please see the following webcams, which provide alternate views of Mauna Loa's Northeast Rift Zone: 

• MKcam - [MKcam] - Mauna Loa's Summit and Northeast Rift Zone from Mauna Kea | U.S. Geological Survey (usgs.gov)
• MK2cam - Mauna Loa's Summit and Northeast Rift Zone [MK2cam] | U.S. Geological Survey (usgs.gov)
